WASH-BOARD.

SPECIFICATION forming part of Letters Patent No. 346,991, dated August10, 1886.

Application filed November 6, 1884. Serial No. 147,292. (No model.)

To all whom it'may concern:

Be it known that I, DAVID JEREMIAH GEORGE, a citizen of the UnitedStates, and a resident of Minneapolis, in the county of Hennepin and theState oi'Mi nnesota, haveinvented certain new and useful Improvements inWVash- Boards, of which the followingis a specification.

Figure 1 is a front elevation, partly in section. Fig. 2 is a sideelevation, partly in section. Fig. 3 is a cross sectional View on theline :v of Fig. 1. Figs. 4 and 5 are enlarged details illustrating themanner of securing the Fig.6 is an en-' bottom tube in the side bars.largcd sectional detail on the line y of Fig. 1. Fig. 7 is an enlargedsectional detail on the line a: 00 of Fig. 1. Fig. 8 isa detail viewillustrating one method of compressing the ends of the back boards.

A A are the side bars, connected together at their top ends by ahead-piece, B, and near their bottom ends by a metal tube,O, the ends ofthe latter passing through the side bars, A Aiand secured therein bybeing upset or flared outward, as shown in Figs. 1 and 5.

In the inner edges of the bars A A grooves a a are cut from their upperends down to the point where the tube 0 passes through them, and intothese grooves the edges of the corrugated metal rubbing-surface D, theback board, E, and the top board, F, are inserted. The

, tube 0 is formed with one edge turnedinward at I), (see Fig. 6,) andits other edge not quite touehingtheturned-in edge, leavingaslitalongits entire length, into which the lower edge of the corrugated metalplate D is inserted, as shown, while its upper edge is held at d in agroove in the lower edge of the top board, F. By this arrangement itwill be seen all the parts are firmly secured together bythe flaringends of thetubeO and the nails in the ends of the head-piece B. The backboard, E, is made of pine or other similar soft wood,a little thickerthan the space which its ends are to occupy in the grooves a a in theside bars, A A, (which are of hard wood,) and its ends are compressed byany suitable means to make them thin enough to beinserted into thegrooves in the rear of the corrugated metal plate. Then when the boardis moistened in using,or when the wood swells again by gatheringmoisture Any means may beused to compress the ends of the boards E F;but I have found a simple cam, G, as shown in Fig. 8, toaccomplish thework very satisfactorily. Care should be taken incompressing the woodnot to destroy the fibers, but si mply compress them sufficiently toenable them to be inserted into a narrower groove than they would enterwithout compressing.

In p u tti ng the boards together the lower edge of one of thecorrugated plates D is inserted into the slit in one of the tubes 0, andtwo of the side bars, A A placed over the ends of the tube, and with theedges of the corrugated plate Din the grooves a a. The outer ends of thetube 0 are straight up to this point of the construction, as shown inFig. 4. The back board, E, is then inserted into the grooves a a andforced down into the rear of the corrugated plate D, and then the topboard, F, is inserted in the same manner and forced down until the upperedge of the corrugated plate D enters the groove at d. The head-piece Bis then nailed or otherwise fastened to the upper ends ofthe sides AAand the ends of the tube O flared outward, as shown in Figs. 1 and 5.The flaring of the ends of the tube may be accomplished by any suitableimplement, and may be done either before or after the back E and top Fare inserted. The small inwardlyturued edge I) in the tube 0 addsstiffness to the tube, and is an important feature of m invention. Byusing this tube I accomplish several very useful results. The lower edgeof the corrugated plate D does not require to be bent in any differentform from that which it has when it leaves the corrugating-machine, asthe slit in thetube Owill receive it in.whatever shape the machineleaves it. The slit also permits the corrugated metal sheet to beadjusted inward and outward, so that the sheets can be adjusted as tolength without cutting them off or stretching them outward.

I also gain a great advantage by compressing the ends of the back andtop boards before inserting them between the side bars, A A, as thenatural swelling of the Wood is thereby clothes being washed. The. otheredge of the slit in the tube comes beneath the corrugated plate D; henceit can never interfere with the operation of the board.

Having thus described my invention,what I claim as new is- 1. Inawash-board, the combination of acor-.

rugated metal plate, side bars provided with grooves to receive the endsof said plate, and a tube secured in said sidebars by flaring its ends,said tube being provided with a longitudinal slit,which receives andholds the lower end of said corrugated plate.

2. In a wash-board, the combination of a corrugated metal sheet, 'D,back board, E,of soft wood and having itsends compressed,and side bars,A A, having grooves a a, adapted to receive the ends of said corrugatedsheet and the compressed ends of said backs, substantially as set forth.

3. The combination of the corrugated metal sheet D, back board, E, sidebars. A A, having grooves a a, adaptcd'to receive the ends of said backand corrugated sheet, tube 0, secured in said side bars by flaring itsends,aud provided with a longitudinal slit adapted to receive the lowerend of said corrugated sheet, top board, F,secured by its ends in saidgrooves a a and provided with a longitudinal slit in its lower edge inwhich the upper edge of said corrugated sheet rests, and a head-piece,B, substantially as set forth.

4. In a wash-board, the. combination of a corrugated metal sheet, D,side bars, A A, having grooves a 41, adapted to receive the ends ofsaidcorrugated metal sheet, tube 0, secured in said bars by flared ends,and provided'with a longitudinalslit through one side adapted to receiveand hold the lower end of said corrugated sheet, and having one edge, b,turned inward toward the interior of. the tube, substantially as setforth.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.

DAVID JEREMIAH GEORGE.
